Probing the Nature of High Redshift Weak Emission Line Quasars: A Young Quasar with a Starburst Host Galaxy

Posted by klaurent MIT

Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Irham Taufik Andika, Knud Jahnke, Masafusa Onoue, Eduardo Bañados, Chiara Mazzucchelli | Summary: We present the discovery of PSO J083.8371+11.8482, a weak emission line quasar with extreme star formation rate at $z=6.3401$. This quasar was selected from Pan-STARRS1, UHS, and unWISE photometric data. Gemini/GNIRS spectroscopy follow-up […]

Hertz-linewidth semiconductor lasers using CMOS-ready ultra-high-$Q$ microresonators

Posted by klaurent Caltech

Kavli Affiliate: Kerry J. Vahala | First 5 Authors: Warren Jin, Qi-Fan Yang, Lin Chang, Boqiang Shen, Heming Wang | Summary: Driven by narrow-linewidth bench-top lasers, coherent optical systems spanning optical communications, metrology and sensing provide unrivalled performance. To transfer these capabilities from the laboratory to the real world, a key missing ingredient is a […]

Imaging spinon density modulations in a 2D quantum spin liquid

Posted by klaurent Berkeley

Kavli Affiliate: Michael F. Crommie | First 5 Authors: Wei Ruan, Yi Chen, Shujie Tang, Jinwoong Hwang, Hsin-Zon Tsai | Summary: Two-dimensional triangular-lattice antiferromagnets are predicted under some conditions to exhibit a quantum spin liquid ground state whose low-energy behavior is described by a spinon Fermi surface. Directly imaging the resulting spinons, however, is difficult […]

A Giant Planet Candidate Transiting a White Dwarf

Posted by klaurent MIT

Kavli Affiliate: Saul A. Rappaport | First 5 Authors: Andrew Vanderburg, Saul A. Rappaport, Siyi Xu, Ian Crossfield, Juliette C. Becker | Summary: Astronomers have discovered thousands of planets outside the solar system, most of which orbit stars that will eventually evolve into red giants and then into white dwarfs. During the red giant phase, […]

Accurate and Lightweight Image Super-Resolution with Model-Guided Deep Unfolding Network

Posted by klaurent Peking

Kavli Affiliate: Li Xin Li | First 5 Authors: Qian Ning, Weisheng Dong, Guangming Shi, Leida Li, Xin Li | Summary: Deep neural networks (DNNs) based methods have achieved great success in single image super-resolution (SISR). However, existing state-of-the-art SISR techniques are designed like black boxes lacking transparency and interpretability. Moreover, the improvement in visual […]

Topological phonon transport in an optomechanical system

Posted by klaurent Caltech

Kavli Affiliate: Oskar Painter | First 5 Authors: Hengjiang Ren, Tirth Shah, Hannes Pfeifer, Christian Brendel, Vittorio Peano | Summary: Recent advances in cavity-optomechanics have now made it possible to use light not just as a passive measuring device of mechanical motion, but also to manipulate the motion of mechanical objects down to the level […]

The Atacama Cosmology Telescope: Modeling the Gas Thermodynamics in BOSS CMASS galaxies from Kinematic and Thermal Sunyaev-Zel’dovich Measurements

Posted by klaurent Tokyo

Kavli Affiliate: David N. Spergel | First 5 Authors: Stefania Amodeo, Nicholas Battaglia, Emmanuel Schaan, Simone Ferraro, Emily Moser | Summary: The thermal and kinematic Sunyaev-Zel’dovich effects (tSZ, kSZ) probe the thermodynamic properties of the circumgalactic and intracluster medium (CGM and ICM) of galaxies, groups, and clusters, since they are proportional, respectively, to the integrated […]

Weyl gauge theories of gravity do not predict a second clock effect

Posted by klaurent Cambridge

Kavli Affiliate: Anthony Lasenby | First 5 Authors: Michael Hobson, Anthony Lasenby, , , | Summary: We consider Weyl gauge theories of gravity (WGTs), which are invariant both under local Poincar’e transformations and local changes of scale. Such theories may be interpreted as gauge theories in Minkowski spacetime, but their gravitational interactions are most often […]

Proper pushforwards on finite dimensional adic spaces

Posted by klaurent Tokyo

Kavli Affiliate: Tomoyuki Abe | First 5 Authors: Tomoyuki Abe, Christopher Lazda, , , | Summary: For any separated, taut, locally of $^+$weakly finite type morphism $f:Xrightarrow Y$ between finite dimensional, analytic adic spaces, we construct the higher direct images with compact support $mathbf{R}^qf_!mathscr{F}$ of any abelian sheaf $mathscr{F}$ on $X$. The basic approach follows […]
